  • disk units capable of reproducing a disk such as a DVD, a CD or the like, or disk units capable of recording and reproducing such a disk
  • a built-in-type disk unit which comprises a tray for placing a disk and is housed in an apparatus casing.
  • Examples of electronic apparatus products of such a built-in type include: a DVD (digital versatile disk) reproduction apparatus (a DVD player); a DVD recording/reproduction apparatus (a DVD recorder); a video/audio apparatus which is a combination of the DVD reproduction or recording/reproduction apparatus and a VCR (video cassette recorder), a cassette tape recorder, an HDD (hard disk drive) or the like; and the like.
  • DVD digital versatile disk
  • DVD recorder DVD recording/reproduction apparatus
  • VCR video cassette recorder
  • cassette tape recorder cassette tape recorder
  • HDD hard disk drive
  • the electronic apparatus having the built-in type disk unit has a tray door which is provided in front of a tray opening provided in a front surface of a unit casing through which a tray is loaded and unloaded, and is opened or closed in association with an conveyance action of the tray.
  • the tray door is provided in a front panel serving as a front outer appearance of the electronic apparatus.
  • the tray which is initially housed in the unit casing of the disk unit needs to be unloaded from the electronic apparatus, and thereafter, the disk needs to be loaded from the outside of the electronic apparatus into the unit casing. Therefore, the user selects and presses one of operation buttons provided on the front panel which is used to unload the tray (open/close button), so that a tray drive mechanism provided in the unit casing of the disk unit acts in a direction in which the tray is unloaded from the electronic apparatus, and therefore, the tray door provided in the front panel is opened in association with the tray unloading action.
  • the tray present in the unit casing is unloaded from the electronic apparatus via the tray opening provided in the front surface of the unit casing and an opening portion opened by the association action of the tray door provided in the front panel.
  • a disk is placed onto the tray unloaded from the electronic apparatus, and thereafter, the user lightly pushes a front end portion of the tray or presses the “open/close” operation button provided on the front panel, so that the tray drive mechanism acts in a direction in which the tray is loaded into the unit casing of the disk unit built in the electronic apparatus. Therefore, the tray is withdrawn and housed into the unit casing via the opening portion of the front panel where the tray door is open, and the tray opening provided in the front surface of the unit casing. Note that the tray door provided in the front panel closes the opening portion in association with the tray loading action.
  • the disk on the tray which has been loaded into the electronic apparatus is rotated while being held slightly above the tray by a turntable provided in the unit casing of the disk unit. In this state, information is written onto the disk or information recorded on the disk is read, using a well-known optical technique.
  • the tray on which the disk is being placed is unloaded from the electronic apparatus by the above-described tray unloading action. In this state, the disk can be removed or exchanged. Thereafter, the tray is loaded into the unit casing of the disk unit by the above-described tray loading action.
  • the disk unit of this type has substantially a U shape such that, as illustrated in FIGS. 5 or 6 , a front surface of a unit casing 101 providing an outer appearance of a disk unit 100 has a bottom surface and both side walls, and a tray opening 102 which is wider than it is long and is open upward.
  • a tray 103 on which a disk is placed and conveyed and which can be loaded and unloaded through the tray opening 102 is assembled with the unit casing 101 .
  • a rotational speed of the turntable provided in the disk unit is, for example, about 2000 rpm (revolutions/minute), which is sufficient for reproduction-dedicated DVD players.
  • DVD recorders capable of recording and reproduction require a rotational speed of as high as about 9000 rpm.
  • the rotational speed tends to be further increased with a recent increase in the speed of digital processing or the like.
  • the rotating disk When the disk on the turntable is rotated at such high speed, the rotating disk may be broken due to damage, though it is considerably rare.
  • the rotating disk When the rotating disk is broken, broken pieces of the disk which are scattered from the tray opening 102 due to centrifugal force are thrown out of the disk unit 100 , and in addition, are likely to be thrown of the electronic apparatus through a tray door (not shown) provided in the front panel, in the case of the structure of FIGS. 5 and 6 .
  • the unit casing 101 of the disk unit 100 is formed of a synthetic resin. Also, an upper front portion of the unit casing 101 has the tray opening 102 which is open upward. Therefore, due to the structure, broken pieces of a disk are easily thrown out through the tray opening 102 without striking the tray 103 or the like.
  • a first protrusion bent to an arc is provided on a surface of the tray along an outer periphery of a disk, and a second protrusion protruding downward is provided on an inner surface of a top plate in a manner which allows it to overlie the first protrusion.
  • An object of the present invention is to provide a disk unit of this type and an electronic apparatus comprising the disk unit which have a simple and inexpensive structure which does not hinder the reduction of thickness, and reliably prevent broken pieces of a disk rotated by a turntable from being thrown out of the disk unit, and in addition, obtain a dustproof effect when a tray is housed.
  • a disk unit with a tray comprises, at least, a unit casing composed of a main body frame open upward and a plate covering the upper opening of the main body frame, and a tray for placing and conveying a disk.
  • a cut of a front surface of the main body frame is provided as a tray opening through which the tray is loaded and unloaded, the cut being wider than it is long.
  • the tray performs a disk unloading action of pushing the tray from the inside of the unit casing via the tray opening toward the front of the unit casing, and a disk loading action of withdrawing and housing the tray via the tray opening into the unit casing.
  • An upper edge frame is provided upside of the tray opening on the front surface of the main body frame, the upper edge frame being wider than it is long, and a protrusion-like extending portion extending higher than an upper edge of the tray opening is provided at a front end portion of the tray, so that the upper edge frame and the extending portion close the tray opening when the tray is loaded.
  • the extending portion provided at the front end of the tray and the upper edge frame provided on the front surface of the main body frame overlap each other in a front-to-rear direction at the tray opening provided in the main body frame (the extending portion is in front of the upper edge frame).
  • the extending portion provided at the front end portion of the tray externally covers the main body frame to close the tray opening.
  • the double structure of the extending portion and the upper edge frame can reliably prevent the broken disk pieces from being thrown out.
  • the double structure of the extending portion and the upper edge frame eliminates a gap which otherwise conventionally occurs between the tray and the tray opening when the tray is housed in the unit casing, thereby making it possible to provide a dustproof effect with respect to the inside of the unit casing.
  • the simple structure in which the extending portion and the upper edge frame overlap each other in the front-to-rear direction allows simple and easy processing and assembly of parts.
  • the extending portion and the upper edge frame overlapping each other in the front-to-rear direction do not have an influence on the height of the disk unit.

  • a front end portion of the plate 4 (excluding both ends thereof) are bent downward and are located on an inner surface (a rear surface) of an upper edge frame described below, to form a bent portion 4 a which is a backing member for reinforcement.
  • a damper (disk clamper) 8 is attached to a position which is closer to the front of the plate 4 and faces the turntable.
  • the damper 8 and the turntable sandwich and hold a disk when the turntable attached to the chassis is lifted by the inclining action of the chassis so that the disk placed on the tray 5 is held up.
  • the damper 8 is freely rotated as with general disk clampers, and clamps a rotating disk on the turntable using a magnetic attraction force generated by a magnet provided in the damper 8 and a magnetic material of the turntable. Note that the damper 8 is attached to the plate 4 , leaving a small gap (clearance) in a vertical direction therebetween so that a rotating disk can be allowed to slightly wobble due to a warp or the like.
  • the tray 5 is different from the conventional tray 103 of FIGS. 5 and 6 in that, as illustrated in FIG. 3 , a protrusion-like extending portion 5 b is integrally formed with a front end portion 5 a of the tray 5 , and the extending portion 5 b uniformly extends from the whole front end portion 5 a so that an upper edge of the extending portion 5 b is higher than an upper edge of the tray opening 6 .
